Clicking the Export button, located above the Table of Results, and directly below the search bar to the far right, will allow you to download a spreadsheet of your current results. Note that the Export button is only active if fewer than 40,000 records are displayed in the Table of Results.
Any fields seen in Record View are available as exportable fields. Use the info buttons next to the field names or visit the Searchable Fields sections of the user guide to find out more.
